Tuberculosis of bones and joints

BILLABLE STATUSNo
IMPLEMENTATION DATEOctober 1, 2015

Code Description

ICD-10 A18.0 is a used to indicate a diagnosis of tuberculosis of bones and joints.

Key Diagnostic Point:

Tuberculosis of bones and joints is a form of extrapulmonary tuberculosis that primarily affects the skeletal system. It is caused by Mycobacterium tuberculosis, which can spread from the lungs or other infected sites to the bones and joints. The condition often presents with localized pain, swelling, and limited range of motion in the affected area. Common sites include the spine (Pott's disease), hips, knees, and other joints. Diagnosis typically involves imaging studies such as X-rays or MRI, along with laboratory tests including sputum cultures and tuberculin skin tests. Treatment usually consists of a prolonged course of antitubercular medications, often requiring monitoring for drug resistance and side effects. Public health implications are significant, as tuberculosis is a contagious disease, necessitating contact tracing and isolation procedures for active cases. The management of tuberculosis of bones and joints requires a multidisciplinary approach, including orthopedic evaluation and possibly surgical intervention in severe cases.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between pulmonary and extrapulmonary tuberculosis
  • Need for comprehensive documentation of symptoms and diagnostic tests
  • Potential for drug-resistant strains complicating treatment
  • Variability in presentation and severity of the disease

Audit Risk Factors

  • Inadequate documentation of diagnostic tests performed
  • Failure to document the specific site of infection
  • Lack of follow-up notes on treatment response
  • Misclassification of the condition as a non-tuberculous infection

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of tuberculosis-related conditions, improving the accuracy of data collection and reimbursement processes. A18.0 provides a clear distinction for tuberculosis of bones and joints, which was less specific in ICD-9.

ICD-9 vs ICD-10

How is tuberculosis of bones and joints diagnosed?

Diagnosis typically involves a combination of clinical evaluation, imaging studies (like X-rays or MRI), and laboratory tests including sputum cultures and tuberculin skin tests.

What is the treatment for tuberculosis of bones and joints?

Treatment usually involves a multi-drug regimen of antitubercular medications over a period of 6 to 12 months, with careful monitoring for drug resistance and side effects.

What public health measures are necessary for tuberculosis?

Public health measures include contact tracing, isolation of active cases, and monitoring for drug resistance to prevent the spread of tuberculosis.
